Plants. 



A very few specimens of Nipadites, and of fruits and seeds similar to "1 p p tst tr 

 those of Sheppey j-u.f.w.m. 



Mr. Wetherell's collection contains a beautiful series of Crustacea from this 

 zone, most of them new ; also several new and undescribed shells. 



Some of the clay at the railway cutting at Copenhagen Fields was found by 

 Mr. R. Jones to be rich in Entomostraca and Foraminifera ; the other zones have 

 not been submitted to so careful an examination, which may account for the 

 comparative poverty of the other lists. From a recent examination of specimens 

 in Mr. Wetherell's collection, Mr. R. Jones has observed that the clay at Finchley 

 yields a very similar group of Foraminifera to that obtained from the clay at Co- 

 penhagen Fields. 



As there is no place in the London Tertiary district where the 

 beds of the fourth or lower zone have afforded the opportunity of so 

 thorough an examination of their organic remains as at Bognor, on 

 the Sussex coast, I have added a list of the fossils found there. This 

 list is chiefly taken from the ' Geology of Sussex ' of the late Mr.
